ENGRAVING OR EMBOSSING MEANS.

Patented Dec 21,1920.

Application filed March 20, 1920. Serial No. 367,308.

To all whom it may concern:

Be it known that we, GEORGE A. DRUOKER, WILLIAM SIECK, Jr., and SAMUELDRUOKER, citizens of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in Engraving or Embossing Means, of which the followingis a specification. f

This invention relates to improvements in engraving or embossing means,particularly adapted though not necessarily limited in its use withprinting presses of the Gordon type, one of the objects of the inventionbeing to provide an improved mechanism of this character embodying apivotally mounted die holder and means adapted to shift the die holderand the die for inking and wiping purposes, and which means is alsoadapted to move the die holder about its pivot into a position to movewith the impression member of the press and cause an imprint to be madefrom the .die.

A further object isto provide an improved device of this character whichwill be simple, durable, and cheap inconstruction and effective andefficient in operation.

To the attainment of these ends and the accomplishment of other new anduseful ob jects as will appear, the invention consists in the featuresof novelty in substantially the construction, combination andarrangement of the several parts hereinafter more fully described andclaimed and shown in the accompanying drawing illustrating thisinvention, and in which- Figure 1 is a side elevationof a Gordon type ofpress, having an attachment connected therewith constructed inaccordance with the principles of the invention.

. Fig. 2 is a horizontal sectional view'taken on line 2-2 with partsomitted.

Referring more particularly to the drawing the numeral 1 designates thereciprocating bed of the press. which is provided at its upper end withspaced bearings 2, and is reciprocable in any suitable manner such as bymeans of a link 1* one end of which is pivotally connected as at 1 tothe support 1, and the other end is pivotally'connected with a crank pin1 of a rotatable element 1.

A die chuck or holder 3 is provided for holding an engraving orembossing die 4 and the die holder has connected therewith a shaft 5which is journaled in the bearings 2 and by means of which shaft andbearing the die holder 3 is adapted to be given a rotatable or pivotalmovement with respect to the bed 1, while at the same time the dieholder 3 is adapted for a reciprocating movement with the bed.

Connected with the end of the shaft 5 is an arm or lever 6 which maybeprovided at its free end with a roller 7.

Connected with the press is a supporting frame 8 which preferablyextends above the press and is provided for the purpose of supportingthe mechanism which cooperates .with the die 41. To the inside surfaceof the supporting frame 8 is attached a cam-shaped rail or guide 9 withwhich the roller 7 on the arm 6 cooperates so as to be moved thereover.The cam or rail 9 is of such a configuration as to cause the die holder3 to assume a substantially horizon tal position as'shown in Fig. 1 ofthe ,drawing when the bed 1 of the press has moved a predetermineddistance away from the platen .10, and it causes the die holder to dropdown or move into an impression position between the bed 1 and theplaten 10, when the bed of the press has moved a'predetermined distancetoward the platen. The cam or rail 9 is also of such a configuration asto cause' the die holder 3 to move into 'a substantially horizontalposition during the first part of the movement of the bed 1 away fromthe platen, to remain in this position until the completion of themovement of the bed in the same direction and for a part of the movementof'the bed 1 toward the platen, at which time the cam rail 9 will causethe die holder 3 to drop down intoa position for making the impressionduring the last portion of the movement of the bed toward the platen.

Supported in any suitable manner by the supporting frame 8 is an inkingroller 11 of the ordinary and well-known construction and which receivesits supply of ink from a suitable fountain 12. The inking roller 11 isarranged adjacent the path of movement of the die 4: when in ahorizontal position and operates to distribute the ink over the surfaceof the die 4 when the same passes under the inking roller either in thebackward or forward movement of the bed 1. Arranged also along the pathof movement of the die 1 is a wipin block 13 of the usual type, ahd overwhich block passes a strip of paper or other suitable material 14 forthe purpose of wiping the excess ink.

from the die."

Obviously, and if desired, any suitable means. may be provided forintermittently advancing the strip 14 so as to present a clean surfaceto the die 4 during the wiping operation.

It is thought that the operation of this invention will be clearlyunderstood from the foregoing description but briefly stated it is asfollows:

As the bed 1 moves from the platen 10, the roller 7 engages the rail orcam 9 causing the lever 6 to rotate the shaft 5. This will in turnbringthe die holder 3 which is connected with the shaft 5, into substantiallya horizontal position and in which position the die 4 contained in thedie holder 3 will pass under the roller 11 to be inked. In the movementof the bed toward the platen the die 4 again passes under the inkingroller 11 and then under the wiping pad 13 which will wipe off theexcess ink. A further movement of the bed toward the platen causes theroller 7 to reach the descending portion of the rail or cam 9 so thatthe die holder 3 will move about its pivot and between the bed 1 and theplaten 10 into a position for making an impression.

, Obviously many changes may be made in the details of construction andin the combination and arrangement of the several parts, within thescope of the claims, without departing from the spirit of thisinvention.

What is claimed as new is:

1. In an engraving and embossing press,

and for pivotal movement with respect thereto, means for moving the dieholder 5 about its pivot into an impression position and for movingthedie holder from the impression position and into an inking and wipingposition, inking and wiping mechanisms for the die arranged along thepath of movement of the die with the support, and means for moving thesaid support to cause the die 'to be operated upon by the said inkingand wiping mechanisms.

3. Incombination with a press embodying a reciprocable bed, a die holderpivotally supported by the bed and for reciprocation therewith, andmeans for swinging the die holder about its pivot from an impressionposition into an inking and wiping position,

a reciprocable bed, a die holder connected.

with said bed for reciprocation therewith and for pivotal movement withrespect thereto, means for moving the bed toward and away from theplaten, means operating during a portion of the cycle of movement of thebed to move the die holder from an impression position into andvmaintaining the die in a substantially horizontal position duringanother portion of the cycle of operation, and inking and wipingmechanism positioned to operate'upon the die during its movement in saidsubstantially horizontal position. 7 1

5. In combination with a press embodying a reciprocable bed, a dieholder connected with said bed for reciprocationtherewith and forpivotal movement with respect thereto, means for moving the bed towardand away from the platen, means operating during a portion of the cycleof movement of the bed to move the die'holder from an impressionposition into. and maintaining the die in asubstantially horizontalposition during another portion of the cycle of operation, and inkingand wiping mechanism positioned to operate upon the die during itsmovement in said substantially horizontal position, the second recitedmeansembodying a cam element and an element co 6perat-, ing therewith,one of said elements being connected with a fixed support and the otherelement being connected with the said die holder, said elements beingmovable rela tively one with relation to the other.

6. In combination with a press embodying a reciprocable bed, adievholder connected thereto for movement therewith and for pivotalmovement with respect thereto,

means for swinging the die holder in one direction about its pivot andagainstthecbed plate into an impression position during the movement ofthe bed in one direction, the said means operating when the bed is movedin the opposite direction toswing the die out of impression position andinto an inking and wiping position and for maintaining the die in suchposition duringa portion of the movement, of the said bed in both directions, means for inking and means for wiping the die.

7 In combination with a press embodying a reciprocable bed, a die holderconnected thereto for movement therewith and for pivotal movement withrespect thereto, means for swinging the die holderin one direction aboutits pivot and against the bed plate into an impression position duringthe movement of the bed in one direction, the said means operating whenthe bed is moved in the opposite direction to swing the die out ofimpression position and into an inking and wiping position and formaintaining the die in such position during a portion of the movement ofthe said bed in'both direc- 10 tions, means for inking and means forwiping the die, the said die swinging means embodying a stationary guideor track and an arm connected with the die holder and movable on theguide or track.

In testimony whereof we have signed our names to this specification onthis 1st day of March, A. D. 1920.
